“When evening approaches, he must wash with water, and when the sun sets he may return to the camp.”
Deuteronomy 23:11 (BSB)
Context Reading
9When you are encamped against your enemies, then you shall keep yourself from every wicked thing. 10If any man among you becomes unclean because of a nocturnal emission, he must leave the camp and stay outside. 11When evening approaches, he must wash with water, and when the sun sets he may return to the camp. 12You must have a place outside the camp to go and relieve yourself. 13And you must have a digging tool in your equipment so that when you relieve yourself you can dig a hole and cover up your excrement.
